Confirmed: the Chicxulub impact caused the K/T extinction
Members of the IUCA and the Team of Micropaleontology of the Universidad de Zaragoza, along with 38 other specialists, publish in the prestigious Journal
Science a review corroborating the theory that the impact of a large meteorite in the Yucatan peninsula caused the mass extinction event of the Cretaceous/Tertiary boundary. The alternative hypothesis supporting a more gradual extinction due to multiple causes (mainly to the unusual volcanic activity of the Deccan, India) is weakened.
